Agent Skills: Composer security check

This skill automates security auditing and vulnerability scanning for Magento 2 applications.

What This Skill Does

1. Dependency Vulnerability Scan

   • Scan composer dependencies for known CVEs
   • Check for outdated Magento core version
   • Identify vulnerable third-party modules
   • Review security patch status
   • Validate PHP version security support

2. Configuration Security Audit

   • Admin panel security settings
   • Two-factor authentication status
   • Session configuration and timeout
   • Cookie security settings
   • HTTPS enforcement validation
   • Secret key usage in admin URLs

3. File System Security

   • File and directory permissions (should be 644/755)
   • Sensitive file exposure checks (.git, .env, etc.)
   • var/log accessibility
   • pub/media upload validation
   • Validate restricted file extensions

4. Code Security Analysis

   • SQL injection vulnerability scan
   • XSS prevention validation (escaper usage)
   • CSRF protection (form key validation)
   • Input validation and sanitization
   • Insecure deserialization checks
   • Hardcoded credentials detection

5. Access Control Validation

   • Admin user audit (strong passwords, MFA)
   • Role and permission configuration
   • API authentication security
   • Customer password policy
   • Failed login attempt monitoring

6. Compliance Checks

   • PCI DSS configuration validation
   • GDPR compliance settings
   • Security headers (CSP, HSTS, X-Frame-Options)
   • Cookie consent and privacy settings
   • Data encryption validation

Security Tools Used

# Composer security check
composer audit

# Magento security scan
bin/magento security:check:now

# File permission check
find . -type f ! -perm 644 -o -type d ! -perm 755

# Search for potential vulnerabilities
grep -r "eval\|exec\|system\|passthru" app/code/
grep -r "unserialize" app/code/

# Check for exposed sensitive files
curl -I https://example.com/.git/config
curl -I https://example.com/.env
curl -I https://example.com/var/log/system.log

MCP Integration

Uses:

• filesystem: File scanning and permission checking
• magento2-dev: Configuration validation
• database: Security-related configuration queries

Scan Output

Risk Classification

• Critical: Immediate security threat requiring urgent action
• High: Significant vulnerability, prioritize remediation
• Medium: Security weakness, schedule fix
• Low: Best practice improvement, low risk
• Info: Security information, no immediate action needed
